Technical Data

alucore-panel

ALUCORE® is an innovative aluminium composite panel consisting of two aluminium cover sheets and a honeycomb core of aluminium.

Boasting the globally recognised ALUCOBOND® trademark, ALUCORE® is also a composite material that can be used for a wide variety of applications from the transport industry to architecture, and has fantastic properties such as extraordinary flatness, a large variety of colours, and high formability.

The product’s aluminium honeycomb core gives the composite panel a high rigidity and an extremely low weight. ALUCORE® therefore has a definite advantage when it comes to projects with high demands on material stiffness – such as façade cladding or roofing where it will be exposed to an extremely high wind load, or for large self-supporting roofs.

ALUCORE® – the first lightweight panel that is a bond for life!

ALUCORE® is an aluminium composite panel consisting of two cover sheets and a honeycomb core of aluminium.
Following in the footsteps of the world-wide established ALUCOBOND® trademark, ALUCORE® is also a composite material for a variety of applications in transport industry and architecture, showing excellent product properties such as extraordinary flatness, large variety of colours and high formability.The aluminium honeycomb core gives the composite panel a high rigidity and an extremely low weight. ALUCORE® therefore provides the decisive advantage where very high demands are made on the material for applications such as façade cladding or roofing, e.g. if exposed to extremely high wind load and for large self-supporting roofs.ALUCORE® is the first lightweight panel that you, too, will absolutely insist as being: a bond for life.

Wind load and permissible panel sizes
The diagrams indicate the available range of panel thickness and permissible range lengths at a given panel width (1250 or 1500 mm), depending on the loads applied.
The diagrams apply to panels supported on four sides (corners fixed). Dimensional values for other systems are available on request.
